IMPROVEMENT IN WATCHMENS CLOCKS.

Specification forming part of Letters Patent No. 43,616, dated July19,1864.

To all whom it may concern:

Be it known that 1, WILLIAM WINTER, of Plainfield, in the county ofUnion and State of New Jersey, have invented a new and ImprovedWatch-Clock; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable any personskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming a part of this snecincation, in whichFigure 1 represents a face view of my in vention, the glass being partlybroken out to fully expose the face. Fig. 2 is a sectional sideelevation of the same.

Similar letters of reference indicate the same parts. I

This invention consists in the application to the face of a clock orwatch ot a movable disk, which is made of slate or other suitablematerialcap tble of receiveing and showingthe mark of a pencil or othersuitable instrumentand marktd with the figures from 1 to 12, the same asthe main dial of the clock, and which revolves with the hour hand undera hole cut into the edge of the lid, which is secured by means of a lockand key in such a manner that said disk or tell-tale dial can only bereached through the hole in the lid, and that when a night-watchnmn orother person having a similar charge is instructed to pass the clock atcertain stated hours, and to make a mark with a pencil on the tell taledial whenever he passes, the employer or superintendent is enabled toread off on said dial at what hours the watchman has passed the clockand made his marks, and byopening the lid of the clock thetell-tale dialcan be readily cleansed and rendered lit for future use.

A represents a clock of the usual construction, with a round, octagonal,or othercase, or made in any desirable manner. Its lid B swings on ahinge, a, and it is provided with a slotted lug, b, to closedown over astaple, 0, through which the ring ot'a padlock can be passed in order tofasten said lid 3 or the lid may be arranged in any other desirablemanner so that it can be closed down and fastened, and that it can onlybe opened by the person having charge of the works or of the place inwhich the clock is to be used. The dial 0 is narked with theliguresl'rom I to .Xll in the usual manner, and the minute hand d andhour-hand e revolve over it in the same manner as on a common clock.

1) is the tell-tale dial, which is made of slate or other suitablematerial capable of rcceivin g and showing a mark made with aslate-pencil or other similar instrument. This tell-tale dial is markedwith the figures from 1 to 12 in reverse order, and it is made torevolve with the same speed as the hour-handof the clock, but in adirection opposite to the same. It must be remarked, however, that bythe addition of another wheel or pinion thetell-tale dial can be made torevolve in the same direction as the hourhand, and in this case thefigures on the same would be arranged in regular order, the same as onthe main dial. Said telltale dial revolves under a hole, f, in the lidof the clock, and this hole is large enough to insert a slate pencil orother instrument to make a mark on the tell-tale dial.

lhe -watchman is instructed to pass the place in which the clock issecured at stated hours, and to make a max k'on the tell tale dialwhenever he passes. If he fails to pass at the proper time and makes amark on the tell tale dial, it will he seen at once when he passed, orif he omits to make his mark the omission will be also observed. 13ythesemeans the superintendent or person having charge of the place isenabled to keep a record of the time when the watchman passes the spotor room in which the clock is put up, and any carelessness 0r remisnessof the watchman will beimmediately. observed, and by opening the lid thetell-tale dial can be easily cleaned and it is ready for future use.

\Vhat I claim as new, and desire to scour v by Letters Patent, isi Theapplication to the face of a clock of the telltale dial 1), made ofslate or other similar material and marked with figures from 1 to 12, incombination with a hole,f, in the lid 13, and with suitable gear-wheelscausing said tell-tale dial to revolve with the same speed as thehour-hand, substantially as and for the purpose set forth.
